使用OpenVINO获取计算设备的全部属性

OpenVINO给计算设备定义了Device properties

使用下面的范例程序，可以获取目标计算设备的全部属性：

#include <string>
#include <vector>

#include "openvino/openvino.hpp"

using namespace std;

void print_any_value(const ov::Any& value) {
    if (value.empty()) {
        cout << "EMPTY VALUE" << endl;
    }
    else {
        std::string stringValue = value.as<std::string>();
        cout << (stringValue.empty() ? "\"\"" : stringValue) << endl;
    }
}

int main(void) {

    cout << ov::get_openvino_version() << endl;

    // -------- Step 1. Initialize OpenVINO Runtime Core --------
    ov::Core core;

    // -------- Step 2. Get list of available devices --------
    std::vector<std::string> availableDevices = core.get_available_devices();

    // -------- Step 3. Query and print supported metrics and config keys --------
    cout << "Available devices: " << endl;
    for (auto&& device : availableDevices) {
        cout << device << endl;
        if (device.find("CPU") != string::npos || device.find("GPU") != string::npos) {
            // ONLY Query supported properties of CPU or GPU
            cout << "\tSUPPORTED_PROPERTIES: " << endl;
            auto supported_properties = core.get_property(device, ov::supported_properties);
            for (auto&& property : supported_properties) {
                if (property != ov::supported_properties.name()) {
                    cout << "\t\t" << (property.is_mutable() ? "Mutable: " : "Immutable: ") << property << " : "
                        << flush;
                    print_any_value(core.get_property(device, property));
                }
            }
            cout << endl;
        }        
    }
    return 0;
}

运行结果如下： Device properties
